So, we can see it is impossible to extract the model parameters \(m_{QQ}\)  and \(v_{QQ}\)  independently from different doubly (triply) heavy baryons. However, the combination of \(m_{QQ}\)  and \(v_{QQ}\) , \(3m_{QQ}/2+8v_{QQ}\) , is ascertainable and can be given directly by the mass of \(\Omega _{QQQ}\) . With this value, we can acquire the masses of doubly charmed baryons. In addition, the parameter of the coupling strength \(v_{QQ}\)  can be estimated by \(v_{Q\bar{Q}}\)  via the relationship \(v_{QQ}/v_{Q\bar{Q}}=v_{qq}/v_{q\bar{q}}\)  [1]}.
Lattice QCD [2]}, [3]}, [4]}, [5]}, QCD sum rules [6]}, and the potential models [7]}, [8]}, [9]}, [10]}, [11]}, [12]}, [13]} predict the masses of \(\Omega _{ccc}\)  and \(\Omega _{bbb}\) , which are around 4800 MeV and 14000 MeV respectively. Taking this central value and \(v_{QQ}\) , we can get the value of \(m_{QQ}\) . Considering the uncertainty of the masses of triply heavy baryons and coupling strength \(v_{QQ}\) , we take a small deviation of both the parameter \(m_{QQ}\)  and coupling strength \(v_{QQ}\) , which can give a range of predicted multi-charmed baryons, as shown in Table REF . We can see the predicted masses are consistent with the results from other theoretical models. The central values and the deviations of \(m_{QQ}\)  and \(v_{QQ}\)  are shown in Table REF . For parameters \(m_{cb}\)  and \(v_{cb}\) , we extract them from the mass spectra of triply heavy baryons (e.g. \(\Omega _{ccb}\)  and \(\Omega _{bbc}\) ) with the same strategy.
